Coral minerals to protect the soil, purify water and grow delicious vegetables.
Sango Studio in the woods
Sango Studio was established in 1987 in the rich forest of Nakijin Village, Okinawa Prefecture.
As a licensed business in Okinawa Prefecture, it started with the purpose of establishing a new project to design coral as food and also to promote employment.
With the support of many experts, we are studying the value of coral minerals and expanding the world of trust.
Hydrogen, which has been attracting attention recently as an ideal antioxidant, we started production in 2009 and was completed as a hydrogen food material and supplement in 2020.
Sango Studio is the world’s largest workshop that carefully manufacture coral products.

Coral Sand Processing for Food
Utilization of coral is extremely valuable raw material that is permitted only to Okinawa Prefecture in the world.
1g sachet of mineral supplement is a product carefully manufactured by experienced professional staff at our Sango Studio. 34 years of history is our pride.
From Okinawa to the World
Coral products were introduced to Sweden 30 years ago and are now delivered to 189 countries such as Europe and United States of America.
Towards healthy aging
With respect to coral minerals, we have committed to contribute healthy aging by providing raw materials with high added value with an extensive knowledge on food, agriculture, forestry, livestock and fishery industry. Based on the 23 years of research on coral biomineralization, we also provide valuable information and advice for product development.
It has been almost 60 years since minerals are believed to be a source of life. We aim to provide the latest information with advice from a wide range of researchers, to strive towards healthy aging for all.

Filtration material to purify and enrich drinking water with minerals.
Coral lives in the water with a temperature lower than that of human body. It contains calcium and many other trace minerals, which makes it possible to take in these ingredients once for all, as an ideal source of minerals. The interaction of trace minerals helps to maintain a well-balanced mechanism for them to function in human body. Among them, calcium ion and magnesium ion are known to be water soluble and easy to be ingested.
Coral Bio-RF
Coral Bio-RF is made from the sand of weathered reef-building coral in the sea of Okinawa. The sands are first sorted by the size of particles, and then dried and sanitized. The high quality minerals in coral make the water tastes better. Coral Bio-RF is available in two sizes of particles: RF-I and RF-II.

Soil conditioner
Supports the growing of crops that are less susceptible to climate fluctuations and failure caused by continuous cropping. It also extends the harvest period and increases volume, as well as improving taste. Because coral is porous, it has strong water retention and drainage properties. It also contains trace minerals that serve as nutrients for microorganisms, supporting an increase in actinomycetes in the soil, and ultimately enhancing soil richness.
Calcium amino acid
A nutritional enhancer made from fermented coral calcium and plant extracts, that is aged with lactic acid bacteria. 100% natural ingredients. Contains calcium and magnesium, soluble silicon and strontium etc.
[Key uses]
Nutritional enhancer for leaves, stems, roots and soil

Soil Balancer
This soil balancer is produced from Okinawa coral. Mixing porous coral grains of various granularity into the soil improves drainage and neutralizes acidic soil. As it contains several minerals in balance such as calcium and magnesium, it strengthens crop resistance to insects and disease. The soil balance is desalinated and dried so there are no salt side effects.
